Driving home from work and my 91 starts to sputter. Wont restart. Towed it home and pulled 3 codes. PO171, PO174, and PO313. Not sure what the 313 is. Says low fuel.
Can anyone help me out? Is it the fuel pump? Low fuel pressure? I think I can hear the pump kick on but not sure. Is this pump in tank or on frame rail? Possibly dirty filter? I know the others are lean bank.
Lots of questions I know. I will get a manual tomorrow but hoping someone can ease my mind tonight.
